Theory and practice: A two-channel automotive radar for three-dimensional object detection
A two-channel automotive Doppler radar for three-dimensional, including azimuth, elevation, and range, object detection has been designed. In order to achieve both high quality AEB performance and low cost, two separate RX-systems (mid-range and short-range) and two TX-antenna arrays oppositely squinted in elevation and separated by half of the operating frequency wavelength along the y-axis, are arranged carefully on a 4-layer RF-PCB. The radar operates in two frequency bands: 24.00 ~ 24.25GHz ISM band and 24.25 ~ 25.65GHz UWB band. A statistical algorithm is applied to determine target elevation.
